Renewable energy: Nanotubes to channel osmotic power

The salinity difference between fresh water and salt water could be a source of renewable energy. However, power yields from existing techniques are not high enough to make them viable. A solution to this problem may now have been found.

A team led by physicists at the Institut Lumière Matière in Lyon, in collaboration with the Institut Néel (CNRS), has discovered a new means of harnessing this energy: osmotic flow through nanotubes generates huge , with 1,000 times the efficiency of any previous system.

To achieve this result, the researchers developed a highly novel that enabled them, for the first time, to study osmotic fluid transport through a single nanotube.

Their findings are published in the 28 February issue of Nature.
